Oh, no, an aquarium full of crickets smells like you would not believe. If you go into a room where somebody’s raising large numbers of them to feed herps it’ll make your eyes water, the penetrating stench is far more objectionable than an equal quantity of ruminant waste.
Of course due to relative volume, it’s a lot easier to handle cricket frass than cow flops, so it’s easier to make cricket raising less “icky”, and you’ve still got a point there.
